DETAILED DESCRIPTION

The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.

One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details.

One or more embodiments of the subject disclosure describes utilizing machine learning systems to regulate environmental conditions within a vehicle to improve driving comfort in accordance with one or more embodiments described herein.

The number of drivers and associated driving time keep increasing rapidly year by year. Driving is an important activity in daily life. Research shows that driving comfort might be spoiled due to various reasons, including foul air, vibration and noise, stress, fatigue, uncomfortable heat and humidity, narrow space and fixed position, etc. Embodiments described and claimed herein utilize machine learning systems that have been explicitly or implicitly trained to learn, determine or infer occupant comfort and dynamically regulate environmental conditions of the vehicle to facilitate achieving occupant comfort. For example, and as will be described in greater detail below, historical occupant comfort levels, occupant preferences, occupant context, ambient conditions inside and outside of the vehicle, vehicle or occupant state conditions, vehicle zones, multiple occupant preferences and comfort, occupant zones and/or intersection areas of occupant zones are some of the many factors that can be taken into consideration by the machine learning system in connection with regulating vehicle environmental conditions to achieve occupant comfort.

The subject disclosure is directed to computer processing systems, computer-implemented methods, apparatus and/or computer program products that facilitate efficiently and automatically (e.g., without direct human involvement) regulating vehicle environmental conditions utilizing machine learning to help achieve occupant comfort. Humans are also unable to perform the embodiments described here as they include, and are not limited to, performing, e.g., complex Markov processes, Bayesian analysis, or other artificial intelligence based techniques based on probabilistic analyses and evaluating electronic information indicative of occupant comfort, determining whether countless multitudes of probability values assigned to occupant comfort exceed or fall below various probability values.

The computer processing systems, computer-implemented methods, apparatus and/or computer program products employ hardware and/or software to solve problems that are highly technical in nature. For example, problems are related to automated processing, determining or inferring occupant comfort. These problems are not abstract and cannot be performed as a set of mental acts by a human. For example, a human, or even thousands of humans, cannot efficiently, accurately and effectively manually apply countless thousands of occupant comfort variables to input points and perform analysis to determine that a probability value assigned to a occupant comfort level exceeds a defined probability value.

In order to provide for or aid in the numerous inferences described herein (e.g., inferring occupant comfort), components described herein can examine the entirety or a subset of data to which it is granted access and can provide for reasoning about or inferring states of a system, environment, etc. from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data.

Such inference can result in construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. Various classification (explicitly and/or implicitly trained) schemes and/or systems (e.g., support vector machines, neural networks, expert systems, Bayesian belief networks, fuzzy logic, data fusion engines, etc.) can be employed in connection with performing automatic and/or inferred action in connection with the claimed subject matter.

A classifier can map an input attribute vector, x=(x1,x2, x3, x4, xn), to a confidence that the input belongs to a class, as by f(x)=confidence(class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hyper-surface in the space of possible inputs, where the hyper-surface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches include, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.

FIG. 1 illustrates a block diagram of an example, non-limiting system 100 that facilitates utilizing machine learning (or probabilistic modeling) to regulate environmental conditions of a vehicle to facilitate occupant comfort in accordance with one or more embodiments described herein. Aspects of systems (e.g., non-limiting system 100 and the like), apparatuses or processes explained in this disclosure can constitute machine-executable component(s) embodied within machine(s), e.g., embodied in one or more computer readable mediums (or media) associated with one or more machines. Such component(s), when executed by the one or more machines, e.g., computer(s), computing device(s), virtual machine(s), etc. can cause the machine(s) to perform the operations described.

In various embodiments, system 100 can be any type of mechanism, machine, device, facility, apparatus, and/or instrument that includes a processor and/or is capable of effective and/or operative communication with a wired and/or wireless network. Mechanisms, machines, apparatuses, devices, facilities, and/or instrumentalities that can comprise non-limiting system 100 can include, but are not limited to, vehicles, planes, recreational vehicles (RVs), vessels, trains, passenger cabins, homes and/or mobile homes and can be implemented at least in part utilizing a variety of devices or appliances including, but not limited to, tablet computing devices, handheld devices, server class computing machines and/or databases, laptop computers, notebook computers, on-board vehicle computing devices or systems, desktop computers, cell phones, smart phones, consumer appliances and/or instrumentation, industrial and/or commercial devices, hand-held devices, digital assistants, multimedia Internet enabled phones, multimedia players, and the like.

The system 100 can include a bus 102 that can provide for interconnection of various components of the system 100. It is to be appreciated that in other embodiments one or more system components can communicate wirelessly with other components, through a direct wired connection or integrated on a chipset. The system 100 can include one or more sensors (e.g., sensors that detect temperature, pressure, light, image, humidity, pollution, smell, smoke, draft, moisture, air quality, particulate, accelerometers, vibration, noise, tone, weight, etc.) that collect information regarding environments external and/or internal to a vehicle, occupants and the vehicle itself and its associated equipment. In some embodiments, context component 106 can collect and provide contextual data regarding the vehicle and/or vehicle occupants. For example, context information such as what activity (e.g., running, swimming, having lunch, sleeping, drinking, etc.) in which an occupant was engaging prior to entering the vehicle can be determined or inferred. Likewise, context information regarding destination of the occupant and/or vehicle, and/or regarding operational information about the vehicle can be collected and provided to the system 100 for analysis in connection with regulating vehicle environment to facilitate occupant comfort.

The context component 106 can, for example, obtain context information from many different sources e.g., an occupant cell phone, calendar, email, GPS, appliances, third parties, the vehicle, etc. The system 100 can include a processor 108 and memory 110 that can carry out computational and/or storage operations of the system 100 as described herein. A communications component 112 can provide for transmitting and receiving information (e.g., through one or more internal or external networks 114 (wired or wireless networks)). A comfort model component 116 can be an explicitly and/or implicitly trained machine learning component trained to determine and/or infer level of occupant comfort and can determine and/or infer adjustments to environment of the vehicle to facilitate occupant comfort. A comfort controller component 120 can regulate one or more vehicle components (e.g., air conditioner, heater, humidifier, de-humidifier, lights, stereo, noise cancellation components, shock absorbers, seats, pressure regulators, filters, pumps, motors, steering components, defogger, de-icer, seat warmers, seat coolers, displays, etc.) based on output from the comfort model component 116 to facilitate achieving a vehicle environment conducive to occupant comfort.

In an example, non-limiting implementation, a driver can enter a vehicle and the context component 106 can determine from a mobile device of the occupant (e.g., via a BLUETOOTH® or other wired or wireless connection) that the occupant just finished a hot yoga class and/or can determine (e.g., via a wearable computing device) that the occupant has an elevated body temperature, is exhausted and in a rush to get home to clean up, dress and attend a meeting in one hour. This context information can be shared with the comfort model component 116, which can perform a probabilistic-based analysis on the context information as well as information from the sensor(s) 104, occupant preference and historical data stored in memory, state information and/or other information that have relevancy to occupant comfort. The comfort model component 116, based on the analyses, can output one or more recommendations that can be utilized by the comfort controller component 120 to adjust environmental conditions of the vehicle to facilitate achieving occupant comfort. For example, the comfort model component 116, based on occupant context information regarding just completing hot yoga, having elevated body temperature, being under some stress and in a slight rush, can generate an inference that the occupant will need a cooler cabin temperature than normal in order to be quickly cooled down and feel comfortable. Additionally, the comfort model component 116 can activate the in seat massage components built into the driver's seat of the vehicle as well as play relaxing music, adjust shock absorbers to provide a softer ride, and adjust lighting in the cabin to effect a calming vehicle environment. The context component 106, and sensors 104 can continually collect data that is analyzed by the comfort model component 116, which will generate determinations or inferences regarding level of occupant comfort. The comfort controller component 120 can continually adjust vehicle environmental conditions to maintain occupant comfort. For example, as the occupant is starting to cool down, the comfort controller component 120 can adjust temperature by raising temperature slightly, reduce force of fans blowing air on occupant, slow down or cease the seat massage, change volume of music, etc. Thus, the system 100 is adaptive and can employ closed or open-looped systems to facilitate maintaining occupant comfort even as conditions of the occupant change. It is to be appreciated that the described and claimed subject matter contemplates and is intended to cover self-driving vehicles.

FIG. 2 illustrates a block diagram of an example, non-limiting system 200 that utilizes machine learning systems (or probabilistic modeling) to regulate environmental conditions within a vehicle to improve driving comfort in accordance with one or more embodiments described herein.

FIG. 2 illustrates an implementation of system 11 that includes a profile component 202 that builds and stores in memory 110 vehicle occupant comfort profiles. An owner of a vehicle is commonly a frequent user of the vehicle, and the comfort model component 116 can build a specific model for the owner as well as respective models for other frequent occupants (e.g., family members, close friends, pets . . . ). Upon identification of an occupant having entered the vehicle, e.g., via facial recognition, seating pattern (e.g., body contours, weight, etc.), biometrics, voice recognition, iris recognition, cell phone, car keys, or any other suitable means for identification and authentication, the profile component 202 can access specific profiles for each occupant of the vehicle that can be utilized by the comfort model component 116 to generate determinations or inferences regarding occupant comfort level and generating recommendations to the comfort controller component 120 to adjust environment of the vehicle to achieve occupant(s) comfort. It is to be appreciated that when multiple occupants are in the vehicle, their respective profiles may conflict in certain aspects, e.g., temperature preference, volume preference, music preference, lighting preference, etc.

The comfort model component can utilize the respective profiles and specific occupant models to achieve a happy medium that achieves levels of comfort suitable for most or all occupants. A utility-based analysis can also be employed where the costs of taking a certain action are weighed against the benefits. For example, if a passenger prefers loud music but such music is a dangerous distraction for the driver who loses focus of attention when exposed to loud music, the comfort model component 116 may determine or infer that the probability and cost of getting into an accident outweighs the benefit of playing such music. The comfort model component 116 can also generate recommendations to the comfort controller to adjust environment of respective zones of the vehicle differently based on occupants within each zone. Additionally, if the comfort model component 116 determines or infers that a driver of the vehicle is fatigued or drowsy, the comfort model component 116 can drive the comfort controller component 120 to make adjustments to the environment (e.g., decrease temperature, increase stereo volume, increase brightness of display and vehicle interior, etc.) to increase level of alertness of the driver. Optionally, the system 100 can provide a notification to the driver to pull over and rest.

FIG. 3 illustrates an alternative implementation of system 100 that includes a pattern recognition component 302. A set of the sensors 104 can include cameras that collect image data inside and outside of the vehicle. The pattern recognition component 302 can be employed to identify occupants, collect facial expression information that can be analyzed by the comfort model component 116 to assess state of occupant(s), e.g., tired, hot, cold, sleepy, alert, sad, happy, nervous, stressed, etc. Based on such determination or inference, the comfort model component 116 can generate recommendations to the comfort controller component 120 to adjust vehicle environment. Additionally, the pattern recognition component can facilitate determining vehicle driving conditions, e.g., the window appears fogged and thus the comfort model component 116 can direct the comfort controller component 120 to defog the windows. The pattern recognition component 302 can detect outside environmental activity, e.g., road conditions, traffic, weather, pedestrians, moving objects, etc. that can be utilized by the comfort model component 116 to instruct the vehicle to regulate operation, e.g., slow down, brake, swerve, switch to low gear, turn on high beams, honk the horn, etc. In another example, the pattern recognition component 302 and possibly a light detection sensor 104 could determine that incoming sunlight is distractive to a driver, and automatically activate window tinting or movement of a motorized visor to mitigate impact of sunlight or glare.

FIG. 4 illustrates an example, non-limiting, schematic representation of a vehicle interior 400. The interior 400 includes a set of occupant seats 402 that can include sensors (e.g., weight, temperature, moisture, etc.) and environmental comfort components (e.g., seat heaters, coolers, massage components, seat adjustment components, vents, blowers, etc.) that can be regulated by the comfort model component 116 to facilitate occupant comfort. Cameras 404 can be situated about the vehicle cabin to collect image information. Vents/blowers 406 can be situated throughout the vehicle to facilitate temperature regulation as well as humidity. Additional sensors 408 can be located at various locations within and outside of the vehicle cabin. These sensors can collect information regarding state of the vehicle and/or occupants (e.g., temperature, light, moisture, pressure, weight, ice formation, noise, etc.). As discussed above, the vehicle can be divided into respective zones (e.g., rear right side, rear center, rear left side, driver side, front passenger side) and information regarding the respective zones and occupants therein can be collected (e.g., via sensors 104, 408 and context component 106) and the collected information analyzed by the comfort model component 116 to infer or determine respective occupant comfort in the zones. Based on the inference or determination, the comfort model component can direct the comfort controller component 120 to adjust environmental conditions (e.g., seat position, seat temperature, blower intensity, zone temperature, zone moisture level, zone noise level, music volume, zone lighting, massage, window tint, visor position, heads-up display, entertainment, wireless signal strength, video, entertainment choices, headset volume, display features, etc.) in respective zones to facilitate occupant comfort in each zone. For example, a family enters the vehicle cabin 400 and the context component 106 can determine that the family is going on an 8 hour car trip to a vacation destination. The sensors 104, along with pattern recognition component 302 can facilitate identifying which family member is seated in a particular seat . The comfort model component 116 can utilize profiles generated by the profile component 202 to generate inferences and determinations regarding suitable environmental conditions for each passenger in their respective zones to facilitate comfort for each family member. Based in part on output from the comfort model component 116, the comfort controller component 120 can adjust each zone respectively to facilitate occupant comfort, e.g., configure seat positions based passenger preferences and context, regulate temperature and humidity in each zone, control type and volume and display of entertainment per passenger preference. The system 100 can continually monitor occupant state, context and comfort levels and dynamically adjust environmental conditions. For instance, if the rear passengers fall asleep, the comfort controller component 120 can raise temperature in the rear, reduce lighting, reduce volume of music, decline seats, etc. to facilitate sound sleeping comfort. Additionally, if the system 100 deems that it is time for the passengers to take a break and walk to circulate blood throughout the body and stretch, the system 100 can send the driver a notification to pull over at the next rest station for a break and to refuel the vehicle.

FIG. 5 illustrates various example, non-limiting body parameters 510 (e.g., blood pressure, heart rate, pulse, skin temperature, respiratory rates, skin humidity, blood oxygen saturation . . . ) and contextual parameters 512 (e.g., in/out car air temperature, in/out car humidity, in/out car pm2 5/TVOC, in/out car db value, in/out car light intensity . . . ) that can be utilized to assess diving car comfort index 514 and regulate car comfort facilities 516. A model can be built for inferring individual occupant comfort degree based on his/her body parameters and contextual parameters. The model can analyze contextual parameters that damage occupant(s) comfort when analyzed occupant(s) are determined or inferred to be un-comfortable. Vehicle facilities can be adjusted appropriately to improve upon the damaging contextual parameters and occupant comfort degree change can be utilized as feedback for optimization.

FIG. 6 illustrates that occupant state 610 and occupant context 612 can factor occupant comfort level 614 and that such state/contextual information can be used by the system 100 to regulate environment of the vehicle to facilitate occupant comfort. For example, if a same occupant is running 620 prior to entering a vehicle, he/she may feel more comfortable at a cooler temperature as compared to if the occupant just finished swimming 624 in a cool pool. Accordingly, data collected from body sensors can indicate an occupant's current body condition which can impact his/her feelings in connection with driving contextual parameters. The system 100 can factor such contextual data (e.g., prior and current state and/or context) to adjust vehicle environmental conditions to facilitate comfort.

FIGS. 7 and 8 illustrate example architectures that facilitate training comfort model(s) and vehicle facility adjustment in accordance with embodiments described herein. A continuous comfort index rather than conventional notion of simplistic comfort/un-comfort is in more accordance with nature of a human's feeling regarding comfort. A continuous comfort index allows for a better occupant experience by allowing for improving upon degree of comfort. For example, the system 100 can suggest adjusting the air conditioning (AC) from 28C to 26C in order to improve one's comfort index from 0.8 to 0.9. A conventional comfort/un-comfort based approach cannot accomplish such real-time automated refinement to facilitate occupant comfort. A continuous comfort index allows finer granular and more cost effective control on vehicle facilities. For example, it can cost less to adjust to improve comfort index from 0 to 0.6 than to a static 1.0. The conventional comfort/un-comfort based approach accomplish such fine tuning due to its static nature.

With reference to FIG. 7, an architecture 700 for training a comfort model 710 is shown. Body and contextual sensors data 710 and driver's actions data regarding car facilities with pre and post facility status 712 are utilized to construct training samples 714. Thereafter, a build 716 is performed to generate a comfort inference model 718 using traditional machine learning (e.g., regression). Inferences regarding driver's comfort 720 are utilized in connection with adjustment(s) 722 (e.g., determine potential driving environmental parameters that can be adjusted to improve driving comfort) and collected car comfort status 724 are utilized for configuration 726 of comfort facilities (e.g., employing feedback regarding inferred driver's current comfort 720) to realize content adjustment in connection with overall facility adjustment 730 to achieve occupant comfort.

Referring now to FIG. 8, an architecture 800 is shown that facilitates achieving and maintaining occupant comfort 802. A comfort inferring model builder 812 builds a model that infers occupant comfort within a vehicle utilizing data receiving from body sensors 814 (e.g., body temperature, blood pressure, heart rate, glucose level, fatigue, drowsiness, alertness . . . ), driving contextual parameter collector 816 (e.g., prior or current activities . . . ), and a comfort facilities status collector 818 (e.g., state of comfort facilities). A driver comfort degree analyzer 815 determines or infers degree of driver comfort utilizing information received from the body sensors 814 and the comfort inferring model builder 812. A comfort facilities adjustment builder 820 receives data from the comfort facilities status collector 818, the driving contextual parameter collector 816 and builds a model for adjusting comfort facilities. A comfort facilities adjustment analyzer 822 analyzes comfort facilities utilizing information from the driver comfort degree analyzer 815, the driving contextual parameter collector 816 the comfort facilities status collector 818 and the comfort facilities adjustment builder 820 to generate adjustments to be made by a comfort facilities controller 824 that regulates vehicle environment (e.g., temperatures, sound, humidity, air circulation, vibration, massage, lighting, etc.) in connection with facilitating occupant comfort 802.

FIG. 9. illustrates an architecture 900 for inferring occupant comfort in connection with a driver's adjustment on car facilities as a “un-comfort” indicator, the number of actions, and gap of facilities status before and after the actions are used for comfort index calculation. For example, one can adjust air conditioning (AC) from 28C to 26C if an occupant feels a little hot, and will adjust the AC to 24C if the occupant is very hot. For example, referring to Table 1 below, exemplary dependent variables (e.g., features) are listed in connection with driving comfort index (0-1).

Referring back to FIG. 9, an architecture 900 for training a comfort model is shown. Body and contextual sensors data 912 and driver's actions on car facilities with pre and post facility status 914 are utilized to construct training samples 916. Thereafter, a build 918 is performed to generate a comfort inference model 920 using traditional machine learning (e.g., regression). Data from the sensors 912 are utilized to continually update the comfort inference model 920.

FIG. 10 illustrates exemplary, non-limiting, construction of training samples 1000 in connection with comfort model training/building in accordance with embodiments described herein. At 1010, combined body and contextual sensors data are sampled at a same time point to form a feature vector (e.g., 75, 35.8, 16, 48, 99, 29, 55, 87, 0.6, 32, 100). At 1020, driver's actions are correlated to the vector is the actions occur within the vector's forward time window 1016. At 1030, the degree to which all correlated actions change status of car facilities are evaluated. At 1040, the current vector and its similar vectors in a backward time window are marked as “un-comfort” (e.g., positive samples). At 1050, other un-marked backward vectors are marked as “comfort” (e.g., negative samples). At 1060, a comfort index is calculated for the samples. It is to be noted that for positive samples the comfort index=1. For negative samples, the comfort index is calculated based on associated facilities adjustment degree.

Referring to Table 2 below and FIG. 11, an example calculation of comfort index for negative sample(s) in accordance with one or more embodiments described herein is presented. At 1100, car facility pre/post adjustment status vectors are built (e.g., pre vector: (28, 50%, 0.8); post vector: (26, 0, 0.5). At 1102, status vectors are normalized based on adjustable range (e.g., pre vector: (0.8, 0.5, 0.8); post vector: (0.6, 0, 0.5) where 0.6=(26−20)/(30−20). At 1104, distance between pre/post vectors is calculated (e.g., Euclidean distance (pre-v, post-v)=0.62). At 1106, comfort index is calculated (e.g., comfort index=1−distance=0.38.

FIG. 12 illustrates a flow diagram of an example, non-limiting computer-implemented method 1200 for determination of damaging driving environmental parameters that can negatively impact occupant comfort. At 1210, body sensor data is obtained of a current “un-comfort” vector. At 1220, “comfort” vectors are clustered by respective body sensor data. At 1230, closest “comfort” clusters by body sensor data are found. At 1240, contextual sensor data of a current “un-comfort” vector is obtained. At 1250, for each cluster representative contextual parameters are calculated. At 1260, a comparison is made with the cluster's representative contextual parameters to identify those parameters worse than a benchmark.

FIG. 13 illustrates a flow diagram of an example, non-limiting computer-implemented method 1300 that vehicle occupant comfort in accordance with one or more embodiments described herein. At 1302, ambient conditions associated with exterior and interior conditions of a vehicle are sensed, including but not limited to sensed information associated with the vehicle and/or occupants of the vehicle. For example, sensed information may include one or more of ambient temperature, light levels, odors, smoke, pollutants, allergens, pressure, moisture, sound levels, noise levels, weather conditions, road conditions, vehicle speed, and direction.

At 1304, occupant context can be determined or inferred (e.g., via a context component 106). For example, occupant context can include prior activities, current activities, stress level, emotional state, destination, upcoming events, attire, alertness, fatigue level, sleepiness level, focus of attention, mood, health state, etc. Extrinsic or intrinsic information regarding an occupant can be collected from a variety of sources (e.g., cell phones, GPS, email, text messages, calendars, appointments, wearable computing devices, cloud-based services, 3rd parties, the vehicle, etc.).

At 1306 the sensed information and occupant context information are analyzed using a trained machine learning system (e.g., comfort model component 116).

At 1308 a determination is made regarding whether or not the occupant is comfortable. For example, a comfort index can be utilized to assess whether the occupant is comfortable or if comfort can be improved upon. If Yes, the process returns to 1302. If No, an environmental regulation system (e.g., comfort controller component 120) is utilized to adjust environmental conditions until the occupant is deemed or inferred to be comfortable.

A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network can comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. Computer readable program instructions for carrying out operations of various aspects of the present invention can be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, configuration data for integrated circuitry, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, or the like, and procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions can execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer can be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection can be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) can execute the computer readable program instructions by utilizing state information of the computer readable program instructions to customize the electronic circuitry, in order to perform aspects of the present invention.

It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. These computer readable program instructions can be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions can also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. The computer readable program instructions can also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational acts to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams can represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks can occur out of the order noted in the Figures. For example, two blocks shown in succession can, in fact, be executed substantially concurrently, or the blocks can sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

While the subject matter has been described above in the general context of computer-executable instructions of a computer program product that runs on a computer and/or computers, those skilled in the art will recognize that this disclosure also can or can be implemented in combination with other program modules. Generally, program modules include routines, programs, components, data structures, etc. that perform particular tasks and/or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the inventive computer-implemented methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as computers, hand-held computing devices (e.g., PDA, phone), microprocessor-based or programmable consumer or industrial electronics, and the like.
